Fisher & Paykel Washer Error Code 235

Error code 235 on a Fisher & Paykel washer indicates a Lid Lock Short Circuit condition detected during Phase 6 of the motor controller's operational sequence. The motor controller sends an activation signal to the lid lock mechanism and monitors the circuit response. When the lid lock fails to engage as instructed, the controller logs error 235 and halts the cycle to prevent operation with an unsecured lid. This is a safety-critical fault because the lid lock prevents access to the drum during high-speed spin cycles.

The diagnostic process centers on measuring resistance across the lid lock's electrical connections. A properly functioning lid lock should read approximately 73 ohms across its terminals. Any reading outside a 5-ohm tolerance window, meaning below 68 ohms or above 78 ohms, indicates a failed or degraded lid lock assembly. A short circuit condition typically produces a resistance reading near zero, while an open circuit will show infinite or very high resistance.

The fault can originate from two primary failure modes: an electrical failure within the lid lock solenoid or wiring harness, or a mechanical jam that prevents the locking mechanism from physically engaging. If the lock's actuator pin or latch is obstructed by debris, a bent strike plate, or a warped lid, the solenoid may draw incorrect current even if the wiring is intact. Both electrical and mechanical failures trigger the same error code, so a thorough inspection of both the resistance values and the physical lock mechanism is essential before replacing components.
